1 Safety precautions
Observe warning labels on the unit as well as the following safety precautions:
1.1 Lockable safety switch
WARNING!
High voltage and rotating fan impeller, risk of personal injury.
Working on/servicing the unit – Shut down the unit via the service
switch in the control equipment, then turn the safety switch to the
0 position and lock it.
NB:
The safety switch is not designed for starting/stopping the unit. Always
use the service switch in the control equipment to start and shut down
the unit.
1.2 Inspection doors
WARNING!
Positive pressure inside the unit, risk of personal injury.
Allow the pressure to drop before you open the inspection doors.
WARNING!
Rotating fan impeller, risk of personal injury. Shut down the unit
via the service switch in the control equipment, then turn the
safety switch to the 0 position and lock it. Wait at least 3 minutes
before opening inspection doors.
NB:
The doors in front of moving parts should normally be locked; there are
no safety guards. Before carrying out work, unlock the doors with the key
provided.
1.3 Electrical connection
WARNING!
Rotating fan impeller, risk of personal injury. The unit must not be
energised until all ducts have been connected.
NB:
Wiring of connections and other electrical work may only be carried out
by a qualified electrician or by service personnel recommended by IV
Produkt.
1.4 Cooling unit/Revresible heat pump
WARNING!
Hot surfaces, risk of personal injury. Shut down the unit via the
service switch in the control equipment, then turn the safety
switch to the 0 position and lock it. Wait at least 30 minutes before
opening the compressor inspection doors.

2.4 CE marking and EU Declaration of Conformity
The air handling units and any incorporated cooling units are CE marked,
which means that upon delivery they conform to applicable provisions in EU
Machinery Directive 2006/42/EC as well as to other EU Directives applicable to the types of air handling units, e.g. Pressure Equipment Directive PED
2014/68/EU.
As certification confirming that the requirements have been met, we provide
an EU Declaration of Conformity, which is available under Documentation
at ivprodukt.docfactory.com, or under Order Unique Documentation at
docs.ivprodukt.com.
The CE marking applies to units that IV Produkt AB manufactures and
supplies in the form of a unit without additional control equipment. For
the CE marking of IV products to apply, the applicable requirements of
the EU Machinery Directive 2006/42/EC and related directives for control
equipment shall be met when installed for the unit.

2.6 Handling of refrigerant
The following information summarises the requirements and guidelines for handling the refrigerant used in cooling units. For further information, see the F-gas
Regulations (EU/517/2014) and the Refrigerant Regulations (SFS 2016:1128).
The purpose of the regulations is to contribute to achieving EU goals for reduced
climate impact in accordance with the Kyoto Protocol.
Operator responsibilities
Generally speaking, the unit operator must:
• Minimise and prevent leakage
• Take corrective action to remedy any leakage that arises
• Ensure that the service and repair of the refrigerant circuit is carried out by a
certified refrigeration technician
• Ensure that refrigerant is handled in an environmentally secure manner and
in accordance with national regulations.
By operator, we refer to the European Parliament’s definition: “...the natural or
legal person exercising actual power over the technical functioning of the equipment and systems...”.
The levels for the various actions to be taken for a system are calculated using
carbon dioxide equivalents, CO₂ e(ton). This figure is calculated by multiplying
the refrigerant’s GWP value (Global Warming Potential) by the filling amount in
kilos. GWP for R410a is 2088. A filling amount of 5.0 kg R410a therefore corresponds to
(5.0×2088)/1000 = 10.44 CO₂ e(tons). The unit is marked with refrigerant quantity and carbon dioxide equivalent.
Leakage inspection and registration
The following applies for single-units with 5 CO₂ e(tons) refrigerant content or
more per circuit:
• Leakage inspections must be carried out by a certified refrigeration technician:
– on installation/commissioning – periodically at least once every 12 months,
i.e. maximum 12 months between inspections
– within one month after any work is performed (e.g. sealing a leak, replacing
a component).
• The operator must record events, such as the volume and type of refrigerant
topped up, refrigerant recovered, results of inspections and work done, person and company who carried out service and maintenance.
If the total refrigerant content is below 5 CO₂ e (tonnes), no periodic leak detection or record keeping is needed, but the requirement for leak inspection during
installation does apply.
If the total refrigerant content of the ventilation system exceeds 14 CO₂ e(tons),
the result of the inspections (inspection report) must be sent to the regulatory
authorities and be in their possession no later than 31 March of the following
year. For a unit that will contain 14 CO₂e(tons) or more, the intended operator
must inform the supervisory authority of the installation well in advance.

3 Technical description
3.1 Envistar Flex air handling unit
The Envistar Flex is manufactured as a modular unit comprising block sections
in various sizes. The versions are named according to the supply air and can be
freely selected: right-hand or left-hand, up or down.
The units are equipped with either a rotary heat exchanger, counter-flow heat
exchanger, plate heat exchanger or run-around coil unit.
The units are also available as single-stacked supply air or extract air units in
sizes 060-600.
The units are usually supplied with integrated control equipment, but can also be
obtained without control equipment.
Cooling units EcoCooler and Cooling heat pump ThermoCooler HP are available
as an option.

4 Wiring instructions and fuse protection
4.1 MX – Complete control equipment and UC – Complete electrical
connection to terminal (without DUC).
Applies to:
• units supplied prewired with complete, integrated Siemens Climatix control
equipment (code MX).
• units supplied without process unit (DUC) but with sensor and damper actuator connected electrically to the terminal (code UC). Fans and heat exchangers are fused and connected electrically to the terminal. The terminal
connections are positioned at a shared place in the unit. For further connection to an external process unit, we recommend using a multi-conductor
cable.
Safety switch
A safety switch is mounted on the air handling unit.
Wiring diagrams
For wiring diagrams for units with control equipment, see the order-unique wiring
diagram supplied with the unit at docs.ivprodukt.com (Control Diagram).
Unit functions, power supply and fuse protection
For power supply to the unit functions and recommended fuses, refer to Order
Unique Documentation at docs.ivprodukt.com (Technical Data and Control Diagram), or the product program IV Produkt Designer.
Recommended fuse protection refers to fuses with type C characteristics.
4.2 MK – Fans and heat exchangers electrically connected to terminal
For units supplied without control equipment but with fans and heat exchangers
connected electrically to terminals (code MK).
Connections to terminal blocks are located on each unit section.
For wiring instructions and recommended fuses, refer to Order Unique Documentation at docs.ivprodukt.com (Terminal Connection and Technical Data).
Safety switch
A safety switch must be fitted and wired on each power supply.
